After the 37-year-old reality star's new We TV series premiered on Friday, February 24, several viewers took to social media to question whether the "before" scenes were actually filmed after she dropped the weight.

"It's obviously obvious that Mama June is wearing a fat face and suit for this show's confessional," one Twitter user captioned a video, in which Mama June appears to be wearing a prosthetic chin below her newly slimmed-down face.

Other eagle-eye fans noticed differences in the former Here Comes Honey Boo Boo star's hair color and pointed out that she looked stiff and didn't move around much. "You can tell some 'before' surgery scenes were filmed after … fake neck & much blonder hair," one viewer noted. Another added, "If she isn't in a prosthetic fat suit, then why can't sure turn her head? She is turning her whole body."

Mama June's new show documents her weight-loss journey and so-called "revenge diet" after her high-profile 2015 split from Mike "Sugar Bear" Thompson. In the series premiere, she was seen exercising outside in an attempt to break the plateau she hit after undergoing gastric-sleeve surgery in May 2015.
